HOOK.

SPECIFICATION forming part Of Letters Patent NO. 600,548, dated March 15, 1898.

Application filed November 20, 1896. Serial 1 (1% modem T0 at whom it may concern:

Be it known that I, JOHN N. MOEHN, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Hooks, of which the following is a specification.

My invention relates to improvements in hooks, and pertains especially to certain specific improvements in that class of hooks described and claimed by me in Letters Patent of the United States No. 529,561, dated November 20, 1894, for improvements in checkhooks. In using the hooks described in said Letters Patent for sustaining heavy weights or great strains I have met with a difficulty in the fact that the coils of the spiral become pressed together under the strain and thus render it difficult and at times impossible to disengage the strap or ring from the hook after the latter has been put to such'use.

The primary object of my invention is, therefore, to provide a form of hook in which one of the coils will receive the entire strain, the function of the other coil beingmerely to prevent the strap or ring from becoming disengaged.

I also have for a second object the provision of means for engaging the free end of a strap or rope, whereby the same maybe first looped into the hook in the ordinary manner and then held at the end to prevent it from slipping out.

As a third object I have provided means for engaging a ring or strap with still greater security by constructing the spiral with a contraction in the space between the coils adapted to permit the removal of a flattened ring or strap when turned edgewise, but to retain it when in any other position.

In the following description reference -is had to the accompanying drawings, in which for convenience in description several of the peculiar features of my invention are shown in separate views, it being understood, however, that all these features may be combined in a single hook adapted to all the purposes expressed.

In the drawings, Figures 1 and 2 are front views showing my invention with two different forms of support. Fig. 3 is a similar view showing a modification of the hook and With dotted lines showing the hook from the side. Fig. 4 is also a front view showing the contraction in the spirals as used with a flattened ring. Fig. 5 is a View similar to that given in Fig. 3, showing that modification of my hook formed with the projection H, the support for the hook being omitted in this view.

Like parts are identified by the same reference-letters throughout the several views.

A and A are supporting rings and plates, respectively, adapted to support my hook. The hook itself is formed of a spiral coil consisting of two membersviz., a supporting member B and a locking member 0, the latter being constructed in advance of the former, thus causing the entire strain of the load to be borne by the member B.

It will be observed that as the respective coils or members B and O of the spiral are in adjacent annular planes the strap or ring may be looped over the member B and then twisted or partially turned edgewise to cause one side of the loop or ring to travel in the space between the members B and C until it clears the end of the member 0, at which point it is turned back to its original position, thus engaging it underneath the end of the member 0 and leaving the ring or loop of the strap engaged in both spirals.

F is a loop formed to engage the supporting-ring A or loop a in the plate A.

G is a V-shaped bend formed in the free end of the spiral and adapted to engage the free end of a strap or cord after a loop of the same has been engaged by the hook.

H is an inward bend or contraction of the spiral forming a narrow space through which a ring or strap may be inserted or withdrawn when turned edgewise, but not when in any other position. A special form of ring adapted to this purpose is shown in Fig. 4, in which the diagonally-flattened portion cl of the ring must be brought to register with the contraction in the spiral in order to permit the ring to pass.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A hook comprising a shank, adapted to engage with a suitable support, and a spiral coil formed with two members B and G, the

member 0 being in advance and at one side B and C, the member C being in advance and I at one side of the member B, and having its free end bent upwardly to form a V-shaped angle, substantially as described. 1

3. A hook comprising a spiral coil formed of two members B and O, the member 0 being in advance and at one side of the member B, and provided with an inward bend or contraction H, substantially as described.

4. The combination of a suitable support,

a progressive spiral coil connected with said support, and formed with two members B and O, the member 0 being in advance and at one side of the member B, and provided with an inward bend or contraction H, together with a ring formed with a recess d and adapted to register with the projection H of the coil 0, when the ring is turned upwardly during the process of insertion through the coil, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.
